A line of severe thunderstorms and tornadoes marched across the US South, peeling away roofs, overturning cars and killing at least 10 people in Tennessee, officials said.
It was the second wave of violent weather to hit Tennessee in less than a week.
Last weekend, thunderstorms and tornadoes killed 24 people in the western part of the state and destroyed more than 1,000 homes and buildings.
The storms raked an area from northern Mississippi to northern Virginia as they moved to the northeast late on Friday after developing from a low-pressure system in the central Plains.
The Nashville suburbs were the hardest hit, with at least eight deaths happening northeast of the city.
Fire Chief Joe Womack said three bodies were pulled from the wreckage of homes in a subdivision of Gallatin, about 39 kilometres northeast of the city.
Steven Davis, who lives about a block from the subdivision, said he ran to a neighbour's home to take shelter in a crawl space when he heard the storm approaching.
"When the tornado came through, the roof was off just like that," Davis said, snapping his fingers. Houses on each side of his street were destroyed.

Tornadoes were also reported in the Nashville suburbs of Goodlettsville, Hendersonville and Ashland City, and in Holladay, about 145 kilometres west of Nashville.
The storms flattened trees, knocked down power lines and damaged homes and other buildings.
